New York duo Cleary Gottlieb Steen & Hamilton and Wachtell Lipton Rosen & Katz have bagged the lead roles on the $27.5bn (£14bn) take-private of telecoms giant Alltel as the boom in big-ticket M&A in the US shows little sign of slowing.

Cleary is advising the buyout consortium, which comprises Texas Pacific Group and the private equity arm of Goldman Sachs Group. Texas Pacific relationship partner Paul Shim led the team for the Manhattan giant, with acquisition finance partner Meme Stowers and corporate partner Duane McLaughlin assisting.
